Mellow Mushroom Cottleville - The Story

Inspired by the aesthetic of the 1980’s, our restaurant celebrates all things Cottleville and Missouri. The 80’s inspiration started with the Delorean, a vehicle that the owner Tammi Hilton’s father drove for many years, because of this, there is a large mural of a Delorean with a license plate reading “88 MPH”. Eye-catching exterior murals were painted by local artists Daniel Burnette and Peat “The Eyez Guy” Wollager. The colorful interior murals were created by artist Ruben Ubiera.

Customer Reviews

I cannot tell you the last time I had chain pizza this good. Went to Mellow Mushroom and were really impressed! Long review to follow. Short review: we'll be coming back. So glad we started with the Elevated Cobb Salad. The chicken and bacon were hot and delicious, but by the time our pizza arrived, we were nearly stuffed at one piece each. The only downside of the Cobb is that it's not available in a small, but this salad is a meal in itself. The Merry Prankster was great; the crust had the perfect crunch and chew in each bite. A delicious combo of freshly sliced chicken, crumbled Italian sausage, fresh and roasted peppers, and the perfect amount of cheese topped by an herb aioli really made this pizza pop. On top of a truly satisfying dinner, our server, Taylor, was helpful and attentive and there were multiple TVs broadcasting the #STLCards game. Pepper flakes, parm, salt, and pepper were on each table, and a convenient outlet in each booth makes charging your phone a breeze. Shockingly enjoyable experience at this chain restaurant, one I'd be happy to have again.

I love this place! I have been going to Mellow Mushrooms for 20 years and have been to them over the country(AL,GA,TN, FL,IN, NC, CO, AZ, and NOW MI! I was excited to see MM has come to the St Louis area. The pizza dough is simply the best and the beer selection is always delightful, Elysian Space Dust is my usual go to, and most MMs have it on tap :) If you like a good pizza and you like like craft beer, you won’t be disappointed.

Food was yummy, service was excellent. Just wish the pizza size descriptions were standard like other pizza joints (in diameter inches) instead of number of slices. Over ordered because of insufficient descriptions.

This place was FU**KING AMAZING* SORRY for the profanity but I rate this place five stars all around. Customer service was excellent. The waiter was helpful, friendly, and funny. Prices and quality of food were excellent I also went to this location late at night, almost before they closed, and their service was still excellent. I haven't had pizza this darn good in a long time. Ever since I last went, I have fantasized when I will take people to this place again Haha. It was that good. The flavor combinations 🙃🤩😮 (one word) WOW❕ I highly recommend this place
